Hi Dolf, two things:

1) There are a number of people on this forum who believe that the PCM-to-HDMI-to-(apodizing)HD621-to-processor route is superior to PCM-to-(non-apodizing)processor. I would let your ears decide; certainly I doubt there is a better HDMI de-jittering solution out there.

2) We don't know how many upsampling MIPS the 808.2 uses and we have even less idea what the relative upsampling MIPS of the 808.2 and 861/G68 apodizing solutions will be. It is not impossible that M will implement different processor apodizing algorithms for stereo and multi-channel inputs if the MIPS are constraining for multi-channel, but not for stereo.
